Develop a network drawing and determine the critical path. How long is the business launch expected to take?Case Report

1. What is the probability for the launch to take longer than 25 days?
2. Assuming that once the company is in operation, the company will generate $3,000/day in profits. The earlier the company is launched, the earlier they can make these profits. Find the optimal launch time and the optimal costs associated with your proposed launch time.
